ASME RA-S-1.1:2024 pdf download online,Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications.
This nuclear standard ASME RA-S-1.1:2024 states requirements for a Level 1 Probabilistic Risk Assessment (PRA) of internal and external hazards while at-power for the evaluation of core damage frequency (CDF). In addition, this standard states requirements for a limited Level 2 PRA sufficient to evaluate large early release frequency (LERF). The only hazards explicitly excluded from the scope are accidents resulting from purposeful human-induced security threats (e.g., sabotage, terrorism).These requirements are written for operating light water reactor (LWR) nuclear power plants.
ASME RA-S-1.1:2024 may be used for LWR plants under design or construction or for advanced LWRs, such as small modular reactors (SMR), but revised or additional requirements may be needed.
